Abstract: Provided are a display device and a manufacturing method thereof. The display device comprises: a substrate; a first electrode and a second electrode disposed on the substrate to be spaced apart from each other; a first insulating layer disposed on the substrate so as to cover at least a portion of the first electrode and the second electrode; and at least one first light emitting element disposed between the first electrode and the second electrode, on the first insulating layer. The first insulating layer comprises: a first sub-insulating layer comprising a first portion including a hydrophilic material and a second portion which is a region of the first insulating layer except for the first portion and includes a hydrophobic material; and a second sub-insulating layer disposed below the first sub-insulating layer, and at least a portion of the at least one first light emitting element is disposed on the first portion.
